Final answer:
At 5-6% dehydration, symptoms include increased thirst, headaches, dizziness, fatigue, low to no urine output, dry and wrinkled skin, increased pulse rate, low blood pressure, and potential fainting, as well as possible weight loss, acid-base balance disturbances, and risk of exhaustion and collapse.
Step-by-step explanation:
At 5-6% dehydration, an individual may exhibit signs such as increased thirst, fatigue, dizziness, headaches, and dry mouth. These symptoms result from water and electrolyte loss in the body that are not adequately replaced. Additionally, physiological effects such as decreased blood volume occur, where the water in cells moves into the bloodstream to compensate, leading to cell shrinkage.
Some specific signs of 5-6% dehydration include low to no urine output, dryness and wrinkle of skin, increased pulse rate, low blood pressure, and potential fainting upon standing up. In more severe cases, there may be weight loss, disturbances in acid-base balance, a rise in body temperature, and the potential for exhaustion and collapse.
